What Is Content Decay? How to Spot and Fix It
Content decay is what happens when a page that once brought steady traffic starts to slide. Clicks drop month after month, often so slowly that nobody notices until a quarterly report. The page didn’t break. The world around it moved: facts aged, competitors improved, and the search results page itself changed.
Key takeaways
- Decay is normal. Every page needs a review date, and money pages need one most.
- Diagnose before you rewrite: lower rankings, fewer clicks at the same rank, and changed intent need different fixes.
- A real refresh changes the substance. Changing the date alone is something Google's guidance explicitly warns against.
- Some decaying pages should be merged or retired, not refreshed.
What causes content decay
| Cause | What you’ll see | Typical fix |
|---|---|---|
| Outdated facts | Old years, prices, screenshots or tool names | Update facts, examples and sources |
| Stronger competitors | Rankings slip as newer, fuller pages appear | Add depth, original examples or a better format |
| Changed intent | The top results are now a different type of page | Rewrite to match, or target a different query |
| SERP changes | Rank is stable but clicks fall | Improve title and snippet; target questions an AI summary won’t fully answer |
| Internal competition | A newer page on the same topic takes over | Merge the two (see keyword cannibalization) |
The fourth cause is growing. Google reported that AI Overviews had over 2 billion monthly users by mid-2025, and Pew Research found users clicked fewer links when an AI summary appeared. A page can hold position one and still lose clicks.

Why content decay matters
Older pages often carry most of a site’s backlinks and authority. Letting them decay wastes that value. On commercial pages, the cost is direct: a pricing guide that drops from position two to seven can cost leads every week. Catching decay early makes the fix small.
Myth vs fact
- MythUpdating the publish date makes Google treat a page as fresh.
- FactGoogle's helpful content guidance lists changing dates to make pages seem fresh, without substantial changes, as a warning sign. Update the content, then the date.
- MythOld content should be deleted to "clean up" a site.
- FactDelete only pages with no traffic, links or purpose. Many old pages are worth more after a refresh than a brand-new page would be.
Example from our work
The cheapest growth on most sites is sitting in pages that already ranked once. I'd rather refresh a guide that slipped off page one than write a new one from scratch. We look for pages losing clicks over a few months, check whether the search intent has changed, then rewrite the sections that are out of date. Changing the date alone doesn't count.
How to find and fix content decay
A quarterly decay review
-
Compare two periods
In Search Console, compare the last 3 months with the same 3 months a year earlier. Sort pages by click loss.
-
Shortlist the losers
Flag pages that lost 30% or more of their clicks and still matter to your business.
-
Diagnose each page
Check whether the drop is in position, in click-through rate at the same position, or in impressions overall.
-
Look at today's results
Search the main query. Note what the top pages do that yours doesn't.
-
Choose the action
Refresh, merge, redirect or retire, using the table below.
-
Re-check in 6 to 8 weeks
Compare clicks and position again, and log what you changed.
| Situation | Action |
|---|---|
| Still relevant, has links, lost ground to better pages | Refresh: new facts, examples, structure and sources |
| Overlaps with a stronger page on your site | Merge into the stronger page and 301-redirect |
| Topic no longer relevant to your business, has links | Redirect to the closest relevant page |
| No traffic, no links, no purpose | Retire it with a 410 or 404 |
What a real refresh includes
Refresh checklist
- Re-answer the main question in the first two or three sentences
- Replace outdated facts, prices, screenshots and tool names
- Add one original element: a worked example, your own data or a clear recommendation
- Update internal links to your newer pages
- Fix or replace broken outbound links
- Then update the "last reviewed" date
Pages written as evergreen content decay more slowly, but they still need a scheduled review. Track the results with the methods in SEO analytics.

Frequently asked questions
How do I know if a page is decaying or just seasonal?
Compare the same months year over year rather than month to month. A seasonal page dips and recovers at the same time each year. A decaying page shows lower numbers than the same period last year, often across several months in a row.
How often should I refresh content?
Review money pages, such as service and pricing pages, every quarter and guides at least every six months. Refresh when facts change or when the page loses a meaningful share of clicks, not on a fixed schedule for its own sake.
Does refreshing old content really help rankings?
It often does when the refresh makes the page more useful, more accurate or a better match for current intent. Superficial edits rarely help. Google's guidance focuses on substance, not on how recently a page was touched.
Should I change the URL when I update a page?
No. Keep the URL so you keep its links and history. Change the URL only if the topic changes completely, and then 301-redirect the old one.
